Even if you're not an HBO subscriber, you can watch the season 4 premiere of "Game of Thrones" -- and we're not suggesting you pirate the show illegally (although apparently, that's a very popular thing to do).

Beginning today and through April 14, all Microsoft Xbox users can watch the first episode of "Game of Thrones" season four for free, courtesy of HBO. The idea, of course, is to hook new viewers so that they go ahead and subscribe to HBO.

HBO has made the premiere episode of "Girls" available for free on YouTube in a similar strategy.
